M1899 Mausers were contracted for by Serbia with both DWM &
Steyr. These rifles are small ring Mausers similar to the M1895
Chilean Mauser, but with a thumb cut in the left side rail. The
M1908 was also produced as a full stocked carbine with turned
down bolt. The model is stamped under a Serbian crest on the top
of the receiver over the chamber.

Theses rifles & carbines were origonally in 7x57mm but most have been
converted to 8x57mm Mauser caliber.

Serbian M1908

Roughly translated to "Oesterreich Waffenfabrique
Gesellschaft Steyr", found on the left side rail (in Cyrillic) on Steyr
made M1899's, etc.
